2 Proposed Changes
The proposed changes to the schema in Clause 2.2 will enable the following more compact encoding in Clause 2.1 of the same AirportHeliport instance introduced in Section 1 to
meet the OWS-6 use case mentioned there. Note that the dateStamp property is replaced by two more specific properties ‘issueDateTime’ and ‘systemLoadDataTime’, which are
named so that we can distinguish between the authorized time of issue of the metadata and the system load time specific to a web service e.g. WFS-T 2.0.
